Trump has ordered the killing in Baghdad of a top Iranian General. Knowing the psyche of the Iranians and remembering the time the US Embassy there , some years ago, was attacked, I would not like to be an American diplomat in Iraq or Iran at the moment,
We should bear in mind that Trump has done what two previous Presidents would dearly love to have done. They - George Bush and Barak Obama - didn't go through with it because they feared the consequences. Donald Trump obviously doesn't fear the consequences, but that's probably because he doesn't fully understand what it is that he has done. It will play well with his supporters at home, but less well in the international community - no members of which were consulted or notified before the event. Qasem Soleimani was a national hero in Iran, but was undoubtedly responsible for the deaths of many American citizens. Indeed, he may well have been plotting the deaths of many more at the time of his death. Trump will see that possibility as a justification for his pre-emptive action, but in technical terms it was an illegal act.
We should be in no doubt that Iran will retaliate, and will do so in a major fashion but how and when it will happen remains to be seen. Any complacency on the part of America or its allies would be a very grave mistake - we are all on the edge of a cliff here.
The trouble is many Americans, some in High places, see any population east of Suez as towel heads (no offence, just quoting).
These "towel heads" were charting the stars when we were still in woad. If they are not already nuclear they are very close.
It is difficult. Until the world is no longer dependent on oil, unlikely to happen during the lifetime of anyone here, sanction are not going to work against a nation that has a major percentage of the world's reserves.
An example of Iran’s revenge is that in July 1988 a US missile destroyer , USS Vincennes accidentally shot down an Iranian airliner with 290 people on board. In Dec 1988 it is probable that Libyan proxies were used to bring down Pan Am 103 with the loss of 259 lives.
The Donald seems to have no longer term strategy to deal with Iran / Iraq
